Jesus said "I thirst" while on the cross to fulfill scripture. By saying this, Jesus revealed three truths: that he was fully human with a physical body that experienced thirst, that he became a substitute for sinners by enduring thirst for our sins, and that his thirst spares us from the torment of thirst in hell. Though Jesus had a human body, he was also God in spirit, as demonstrated through his miracles. In uttering "I thirst," Jesus experienced the thirst of separation from God the Father while providing salvation for humanity.
